2020-05-18
We’ve updated and optimized the following features based on feedback from RoboMaster users around the world:
Lab
1. Adds new interface for playing custom audio. Play your custom audio recordings using the Intercom.
2. Adds new power acquisition and chassis rotation interfaces.
3. Adds an interface for stopping servos (RoboMaster EP only).
4. Adds new function for expanding and collapsing blocks. Viewing the code for Scratch blocks is now much easier!
5. Adds new function for saving block locations. Save a Sratch block’s location on the programming interface so you can easily find and use it next time.
Push Notifications
1. Adds new push notification function. Interact directly with RoboMaster developers! Enable push notifications on your phone to gain access to fun new features from the developers behind RoboMaster, like new games and programs, or offline events such as robotics club meetings and multiplayer battles. Don't miss out!
RoboMaster EP Compatibility
1. Adds the RoboMaster EP image to the home screen.
2. Adds new Load Mode function for the robotic arm. Enabling Load Mode allows the robotic arm to grab heavier objects.
3. Adds new robotic arm attitude display to the FPV view. View the real-time attitude of the robotic arm on the FPV interface (Tip: Enable in Settings).

Other
1. Optimizes compatibility with RoboMaster S1 and EP.
2. Optimizes block descriptions in Lab.
3. Reduces installation package size.
4. Fixes certain user experience and functionality issues.
Your experience is important to us!
Note: After updating the app to version 1.1.2, don't forget to update the robot’s firmware to the corresponding firmware version. Otherwise, you won’t be able to connect the robot to use the Solo, Battle, and Lab functions. (RoboMaster S1 firmware version: 00.06.0100 or later; RoboMaster EP firmware version: 01.01.0100 or later)

Screen upside down
Please fix it. This app's screen is upside down when I am using it on an ipad pro with a keyboard. I didn't lock screen rotation on my ipad. The screen can't rotate with my device. When I put my ipad with keyboard on desktop, the volume buttons are upwards. But this app's screen is upside down. It's a problem when I type codes in this app. Beside, It's a nice app.
cybersoul,
Can no longer connect via router on iPad Pro
Other reviews have noted the issues and the positives of a solid robot and a weak app. I can connect to both an S1 and EP core using the latest os on iPhone 12 Pro, but not on an iPad Pro since the last iPadOS update. It worked before, but something has been broken. Sadly, even on a large phone, the programming text is too small for me to use that. I can only connect via WiFi access point, which will have to do for programming. In addition, please fix the keyboard issue!
Gpvillamil,
Great product, good app, shows potential
The Robomaster S1 is a great product. It is one of the most interesting and well-engineered robots out there.
The companion app is also pretty solid. The Solo mode lets you drive around, the Battle mode sets up multi-player battles with scorekeeping, and the Lab lets you create programs in Scratch and Python.
It would be great if the Battle feature supported teams, currently it is more of a free-for-all (still fun!).
One of the earliest updates fixed the screen orientation feature, so now you can use an external keyboard for coding with the iOS app.

hipeepimdoofy,
Device turned around
When you go in the app the screen turns upside down and then you have to keep the screen upside down you can not fix it developers please fix it
yes to you,
It is so fun
You can program your robot to do amazing things and it can take videos and pictures. And you can control the speed of the robot thanks for the app
Dox_Hans,
Awesome app!
You can tell that they worked hard on the website. Just writing this to share my opinion.
ERY18385792,
Great build but can’t connect
Building the device was great but, once I was done and the battery was charged I tried to connect to the device using the app. I tried to use both, the WiFi and router to connect to my device but it wouldn’t work.
Papersoldier007,
Awesome app
Me and my brother built each other‘s robot then we were playing battles it’s really fun. you just need to buy the DJI Robo master S1
blueoverseas,
Sloppy
This review is for the Robomaster EP Core.
The app can’t connect to the robot via a router. In comparison, the Windows app finds the robot on the network and connects to it without any problem.
In “Lab” mode:
- the “Road to Mastery” tutorials are designed for the Robomaster S1 with a gimbal and blaster which the EP Core doesn’t carry.
- major educational materials in the “RoboAcademy” section are inexistant: video courses and programming guide links don’t work. Anyway, they promise you’ll have access to custom learning materials when you buy the EP Core. But they are nowhere to be found on DJI websites except for the syllabus summary.
Very disappointing.

hahdhdhjd,
Cant open app
I was able to use this app before but I can’t seem to open it now. I tried deleting it and I was able to use the app up to accepting terms and conditions, after accepting it, the app would close. Then after that every time I tried to use the app it closed after a couple seconds.
